you lifting a 14 foot snake 5 ft in the air to get it in there? or chunking substrate up there? also, thats a lot of weight to support (enclosure, substrate, appropriately sized water bowl, and the snake. Not saying it is impossible but keep it in mind. and yeah, getting to the back of a 7 foot deep enclosure with only 5 feet of headroom means hands and knees. also, a snake enclosure directly on the floor means you might not see much of the snake without getting down on your knees.
